Failed: [2017] Can't open named pipe to host: . pipe: MySQL (2)

Can't open named pipe error
If you use a MySQL Version 3.22 server on NT with the newest MySQL client programs, you will get the following error:

error 2017: can't open named pipe to host: . pipe...
This is because the release version of MySQL uses named pipes on NT by default. You can avoid this error by using the --host=localhost option to the new MySQL clients or create an option file `C:\my.cnf' that contains the following information:

[client]
host = localhost
Starting from 3.23.50, named pipes are enabled only if mysqld-nt or mysqld-max-nt is started with --enable-named-pipe.
